Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a covering device for sealing an upper surface opening of a water purifier for purifying and storing raw water in a facility for filtering water.

[Conventional technology]

The filtering device will be described in detail in the section of Examples, but it is configured to occasionally wash the filtering material by using the water of the water purification conduit,
In order to suck up water, a pipe projects into the inside of the upper surface of the water purification conduit, and the pipe needs to reciprocate along the longitudinal direction of the water purification conduit. For these reasons, conventionally, a rubber cover is attached to the upper opening of the water purification conduit, one side edge of which is fixed and the other side edge is covered as a free end.

[Problems to be solved by the device]

With the cover provided as described above, the portion of the cover into which the pipe projects is bent by the pipe,
As the pipe moves, its bent part also moves sequentially, and after passing through the pipe, the bent part returns to a horizontal state due to the weight and elasticity of the cover, and seals the upper opening of the water purification conduit. , When the cover bends,
It is inevitable that the dust caught on the cover will fall into the clean water ditch, and since the pipe is repeatedly moved, fatigue of the cover progresses as it bends and stretches, and the free end of the cover gradually opens. There is a problem that the function as a cover is reduced early because it is no longer closely attached to the rim.

The present invention solves the above-mentioned problems, provides a reliable sealing function for a long period of time, and provides a clean water drain coating device for a filtration facility, which is intended to reliably prevent dust from falling into the clean water drain. To do.

[Means for Solving the Problems]

The solution according to the present invention is to attach a fastener element row for slide fasteners to opposite edges of both left and right covers fixed to both edges of a water outlet of a water purifier, and to attach a pair of sliders to each other across both fastener element rows. When sliding in the direction of approaching each other, both fastener element rows are inserted so that they mesh with each other, and both sliders are spaced and fixed to the traveling platform on the water purification conduit, and the opening of the cover is provided between both sliders. The two fastener element rows in the opening are engaged with the supporting portion provided on the traveling base so as to stand upright.

[Action]

Therefore, since both sliders slide on the fastener element row in the same direction as the traveling platform moves, the opening opened between both covers is located below the traveling platform and moves in the same direction. In addition, since the unengaged fastener element row of the opening is guided in the running direction while being erected and held by the support portion during the movement, the cover of the opening is held in a downward concave shape to prevent dust from entering. Moreover, since the fastener element row is engaged and closed except the opening of the cover, the opening of the water purification conduit is always closed.

[Embodiment] Since the present invention is related to the filtration equipment, the filtration equipment will be described first.

Fig. 1 is a plan view of the filtration equipment, with the filtration pond 1 in the center.
Is equipped with a raw water culvert 2 into which one side of the sewage flows in over the entire length of the filtration basin 1 in the longitudinal direction, and the other side is provided with a water purification culvert 3 for storing the same purified water. In addition, a water purification basin 4 is provided at one end of the water purification culvert 3, a drainage gutter 5 is provided above the raw water sluice 2 side of the filtration basin 1, and a drainage basin 6 is provided continuously to the end of the drainage gutter 5. . Further, as shown in FIGS. 1 and 5 to 7, the bottom of the filter basin 1 is divided into a plurality of parts laterally with respect to the longitudinal direction by a partition plate 7, and a filter material layer 8 is provided in each partition part. Yes, sewage flows into the filtration basin 1 through the intake 9 provided at the upper part between the raw water conduit 2 and the filtration basin 1,
The purified water is taken from the bottom of the filter basin 1 to the water culvert 3 and the outlet 10
It is supposed to flow in through.

By the way, since it is necessary to wash the filter medium layer 8 from time to time to restore the filtration capacity, the filter medium layer 8 is washed by the washing device 11 using the water in the water purification conduit 3, and the wash water is drained into the drain gutter 5
It is designed to be discharged to the drainage box 6 through.

The cleaning device 11 has rails 1 laid on both sides of the filtration pond 1.
It is installed on the traveling platform 13 which is placed on 2, 12 and has a length to reach the top of the water purification conduit 3. As shown in FIG. 5 to FIG. A cleaner box 14 that covers the space is hung vertically from the traveling base 13 to remove the cleaner box 14.
A water spray pipe 15 for spraying water in a shower shape and a water collection pipe 16 for sucking water are installed in parallel inside the water collection pipe 16.
A drainage pump 18 driven by a drainage motor 17 provided at 13 is connected, and a first drainage pipe 19 from the pump 18 is piped into the drainage gutter 5. On the other hand, a backwashing pump 21 driven by a backwashing motor 20 provided on a traveling platform 13 is vertically installed in the water purification culvert 3, and the backwashing pump 21 is vertically moved from the middle through the first switching valve 22. Is equipped with a water supply pipe 23, and at the tip of the lower water supply pipe 23, there is a brim 24 that is in close contact with the lateral wall of the water purification culvert 3 while maintaining watertightness. The upper water supply pipe 23 bypasses the traveling platform 8 and is a motor. -Supplied surface washing pump 25 and second
It is connected to the sprinkler pipe 15 via a switching valve 26. Further, a drain pipe 27 branched from the second switching valve 26 is connected to the drain gutter 5.

The first switching valve 22 causes the water from the backwash pump 21 to flow to both upper and lower water supply pipes 23, and the upper and lower water supply pipes 23 are “through”.
However, it is switched to the case of blocking the flow to the backwash pump 21. The second switching valve 26 switches the flow of water from the water supply pipe 23 between the sprinkler pipe 15 side and the second drain pipe 27 side.

When the filter material layer 8 is washed, the traveling base 13 is moved to cover the space between the adjacent partition plates 7 and 7 with the cleaner box 14, and then the drainage pump 18, the backwash pump 21 and the surface wash pump 25 are installed. When driven, the water inside the cleaner box 14 is discharged, and at the same time, the water in the water purification culvert 3 is sprayed from the sprinkler pipe 15, and the water in the water purification culvert 3 is taken out through the outlet 10 to the filtration pond. The filter material layer 8 is washed by inflowing it from the bottom of the filter material 1. After cleaning in this way, the first and second switching valves 22 and 26 are switched together to stop the injection from the sprinkler pipe 15 and absorb the water remaining under the filter medium layer 8 from the outlet 10 to drain the drain gutter 5 The cleaning of one filter material layer 8 is completed by discharging it to the drainage box 6 through. The above washing operation is performed by sequentially moving the traveling table 13 for each filter material layer 8.

As described above, the backwash pump 21 of the cleaning device, the water supply pipe 23, etc. are inserted from the traveling base 13 into the water purification culvert 3 through its upper opening, and these backwash pump 21, water supply pipe 23, etc. Since it moves in the longitudinal direction of the water purification conduit 3, it is necessary to provide an opening on the upper surface of the water purification conduit 3 over the entire length.
On the other hand, it is necessary to prevent the entry of dust into the water purification conduit 3 through this opening.

The water purifier coating device according to the present invention is intended to achieve this object by the structure shown in FIGS. 1 to 4.

Covers 28, 28 made of a strong sheet which is rich in watertightness, not limited to rubber, are adhered over the entire length of both edges of the upper surface opening of the water purification culvert 3, and the edges of the opposite sides of the both covers 28, 28 are closely attached. By attaching the fastener element rows 29, 29 for slide fasteners over the entire length and sliding the pair of sliders 30, 30 over both fastener element rows 29, 29 in the direction in which they approach each other, both fastener element rows The sliders 30 and 30 are fixed to the lower ends of the arms 31 and 31 vertically extending from the front and rear portions of the traveling base 13 so that the sliders 3 and 29 can be engaged with each other.
An opening 32 is provided between 0 and 30, and support portions 33 and 33 are vertically provided from left and right portions of a portion of the traveling platform 13 facing the opening 32, and the support portions 33 and 33 are provided on the left and right sides between the openings 32.
